A hand-held dental device that includes a chuck for attaching a rotary dental endpiece (e.g., drills, burs, reamers) intended to be used in dentistry to bore/excavate bones, teeth, and tough tissues. The device is remote from the power source (an AC-powered motor) and is connected by a flexible drive system (e.g., a Bowden cable) that transfers the rotational power; the endpiece(s) are not included. This is a reusable device.
